Abstract
The utility model relates to a keystoke mechanism, comprising a keystoke and a shell containing the keystoke; the shell is a cup cavity, a spring sheet is arranged at the bottom part of the cavity, and the upper end of the spring sheet is provided with the keystoke with a cross-shaped section; the shoulder part of the keystoke and a top end wall of the shell are at the same plane, and a pressure plate is arranged; an internal concave shape like a pot body clamped between the keystoke and the spring sheet is arranged between the pressure plate and the top end wall of the shell in a clamping way, thus forming an elastic packing body contained in a keystoke cavity.
Description
Technical field
The utility model relates to a kind of press button mechanism.
Background technology
CN200620134561.1 has announced a kind of " press-key structure ".Its purpose provides a kind of press-key structure with spherical arc contacting metal shell fragment.Its technical scheme: this press-key structure, in order to push a metal clips triggering signal, include a key body and and press bar, press the bottom face cambered surface spherical in shape of bar, press bar and be right against a metal clips, force in pressing body and make and press bar and be pressed on the metal clips, spherical arc contacts for point with metal clips, make can drop on when pressing bar and pressing metal clips effectively by in the nip, can elastic recovery after removing the application of force to guarantee metal clips.This press-key structure cooperates small metal clips, press the bar bottom face and adopted spherical circular-arc design, make to press between bar and metal clips and contact for point, thereby make that pressing bar has higher accuracy, a little size or assembly error can make that still pressing bar is pressed on effectively by within the nip, damages to guarantee the unlikely generation permanent deformation of metal clips.This metal clips has one effectively by nip, this external diameter that presses bar less than this effectively by the external diameter of nip.Its weak point: button is not dustproof, non-watertight, and button is short useful life.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, provides a kind of by the elastic packing body structure is set, and causes button to avoid into water, wet goods impurity, so that button is dustproof, and waterproof improves the button press button mechanism in useful life.
The purpose of this utility model can reach by following measure:
This press button mechanism, the housing that comprises button, ccontaining this button, its special character is: described housing is a cup-shaped cavity, its cavity bottom is provided with shell fragment, shell fragment upper end, and to be provided with the cross section be criss-cross button, described button two shoulders and housing top end wall are same plane, and respectively establish a pressing plate respectively, between two pressing plates and the housing top end wall respectively folder establish one be interposed between button and the shell fragment and concave shaped like the pot body to form the elastic sealed body of ccontaining button cavity.
The purpose of this utility model can also reach by following measure:
Described shell fragment is made up of an arcuate tab.
Described elastic sealed body is the upwards vertical protuberance and stretch out respectively with cavity, cavity end that planar base surface is vertical configuration and the elongated end parallel with planar base surface formed in its end respectively by a planar base surface.
The utility model has following advantage compared to existing technology:
1, button is dustproof, waterproof.
2, improved button useful life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
See also shown in Figure 1, this press button mechanism, the housing 1 that comprises button 5, ccontaining this button 5 is a cup-shaped cavity, its cavity bottom is provided with shell fragment 3, shell fragment 3 upper ends, and to be provided with the cross section be criss-cross button 5,5 liang of shoulders of described button and housing 1 top end wall are same plane, and respectively establish respectively be folded with respectively between a pressing plate 4, two pressing plates 4 and housing 1 top end wall be interposed between button 5 and the shell fragment 3 and concave shaped like the pot body to form the elastic sealed body 2 of ccontaining button 5 cavitys.Described shell fragment 3 is made up of an arcuate tab.Described elastic sealed body 2 is the upwards vertical protuberance and stretch out respectively with cavity 21, cavity 21 ends that planar base surface is vertical configuration and the elongated end 22 parallel with planar base surface formed in its end respectively by a planar base surface.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
Claims (3)
1, a kind of press button mechanism, the housing that comprises button, ccontaining this button, it is characterized in that: described housing is a cup-shaped cavity, its cavity bottom is provided with shell fragment, shell fragment upper end, and to be provided with the cross section be criss-cross button, described button shoulder and housing top end wall are same plane, and establish a pressing plate, be folded with between pressing plate and the housing top end wall one be interposed between button and the shell fragment and concave shaped like the pot body to form the elastic sealed body of ccontaining button cavity.
2, according to the described press button mechanism of claim 1, it is characterized in that: described shell fragment is formed by one spherical.
3, according to the described press button mechanism of claim 1, it is characterized in that: described elastic sealed body is the upwards vertical protuberance and stretch out respectively with cavity, cavity end that planar base surface is vertical configuration and the elongated end parallel with planar base surface formed in its end respectively by a planar base surface.
